Specification of Letters Patent. Application filed November 4, 1908.

Patented Jan. 4, 1910. Serial No. 461,002.

To all whom it may concern:

Be it known that I, Josern CECIL HAMLIN GERST, Jr., a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Carriers, of which the following is a specification.

My invention is an improvement in car riers, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

The object of the present invention is to provide a device especially adapted for removing litter and the like from stables, the carrier consisting of a fixed portion which is adapted to take the place of ti e ordinary gutter at the rear of the stalls, and an elevator proper for receiving the litter from the fixed or horizontal portion and depositing it in a pile remote from the stalls.

Referring to the drawings fori'ning a part hereof, Figure 1 is a plan view of my improvement. Fig. 2 is a side View. Fig. is a sectional view elevator proper; scraper.

The present embodiment of the invention comprises a horizontal portion and an elevator proper, the horizontal portion consisting of a base or bottom 1, and side boards 2, secured to the side edges of the bottom in any suitable manner, and the side boards may if desired be provided with extension side boards 3, which are secured to the side boards proper by straps 4.

The horizontal portion is preferably made in sections, as shown in Fig. 2, and the sections may be secured together by means of straps 5 also shown in the said figure. At one end of the horizontal portion a shaft 6 is ournaled, said shaft being provided with spaced sprocket wheels 8, and the shaft 6 is journaled in bearings 9, which are slidable in slots in brackets 10 secured to the side boards, springs 11 being arranged between the bearings and the ends of the and Fig. 4 is a detail of the in its outermost position.

At one end of the horizontal portion, is hinged an adjustable portion consisting of a bottom or base 14, and side boards 15 connected with the bottom, and at the outer end of the movable section is journaled a shaft 16, provided with spaced sprocket wheels 17, over which and the sprocket wheels of of the upper end of the the shaft 6, pass sprocket chains 12, the chains being connected at spaced intervals by cross bars 13, the one run of each chain passing above the base board, and the other run below as shown in Fig. 3.

The side boards 15 of the adjustable section, are hinged to the side boards 2 of the horizontal section, and the side boards of the horizontal section are provided with aprons 7, secured to the side boards at 18, and extending over the adjustable section where by to guide the material from the horizontal section to the movable section.

Idlers 19 are journaled on stud shafts 20, projecting from the inner faces of the side boards of the horizontal section throughout the length thereof, the idlers supporting the lower runs of the sprocket chains.

of the side boards of the horizontal section and of the adjustable section above the upper runs of the chains, and the said strips extend from end to end of each of said portions. Such strips are for the purpose of guiding the chains and also for preventing litter from becoming entangled therewith. Wheels 22 are journaled at the junction of the horizontal portion with the adjustable portion for engaging the upper runs of the chains whereby to retain said chains in position when the adjustable portion is moved. A swinging shield 24 is pivoted as at 25 between the side boards of the horizontal section, at the opposite end from the movable portion, to prevent the litter from escaping at the adjacent end of the carrier.

- The shaft 16 is extended at one end as at i 27, beyond the side boards, and is provided I with a sprocket wheel 28, over which passes a sprocket chain 29, connecting the said wheel with a sprocket wheel on a shaft 31. The shaft 31 is provided with a second sprocket 32, which is connected by a sprocket chain 33, with a sprocket wheel 34, on a stud shaft 35, on a standard 36 extending upwardly from the horizontal portion of the carrier.

The standard 36 has its lower end received in bearings 37, secured to the side boards of the horizontal portion by bolts 38, and the standard is braced by a brace 39, connected with the standard as at 40', and with the side boards of the horizontal portion as at 41.

The sprocket wheel 34 is provided with a crank 42 whereby to rotate the said wheel, l and it will be evident that when the wheel is Strips 21 are secured to the inner faces rations 45, which are adapted to be. engaged by a bolt 46, traversing one of the perforations and the side boards of the movable portion of the carrier whereby to retain said portion in its adjustable position.

It will be evident that by engaging the pin with different bolts, the side board may be maintained in a higher or lower position as may be desired.

In operation, the carrier as before stated is arranged behind a row of stalls, the stationary portion may be of any suitable length being formed of connected sections I as stated, and the litter from the stalls is swept into the trough formed by the base and the side boards. V hen a sufiicient amount of litter has been placed in the horizontal portion, the crank 42 is rotated, and the litter is moved from the horizontal portion over the movable portion to the dump. As the dump pile increases, the movable portion is elevated and retained in its ad justable position bythe standards 43.

The movable section is provided With handles 47, for convenience in lifting the same, and adjacent to the outer end thereof, depending arms 4-8 are pivoted to lugs 49 on the sides of the carrier, and the free ends of the brackets are off-set outwardly as at 51, and are connected by a cross bar 52, as shown in Fig. 5.

The cross bar acts as a scraper, to clean the conveyer as it passes over the end of the movable portion of the carrier. Reinforcing strips l9 are bolted to the bottom of the carrier by bolts 50.

The carrier may be composed of any suitable material, such as wood reinforced or sheeted on the inner face and bottom. with sheet metal and the cross bars 13 are made of iron piping.

I claim:

A device of the class described, comprising a trough, an endless carrier supported by the trough, said carrier comprising spaced chains and cross bars connecting the chains at intervals, and a. scraper at the un der side of the movable section over which the carrier pass-cs, said scraper having a r duced portion depending between the chains.
